# Pay for blockchain data and analytics

Access on-chain data — token prices, wallet analytics, DEX trades, stablecoin flows, and smart contract events — from any MPP-enabled blockchain data provider. Pay per query with stablecoins on Tempo.

## The problem

Blockchain data APIs gate access behind API keys, developer accounts, and monthly subscription tiers. Agents that need to query multiple providers — one for wallet balances, another for DEX analytics, a third for historical prices — must manage separate credentials and billing for each. Free tiers run out fast, and upgrading means committing to monthly plans before knowing actual usage.

## How MPP solves it

With MPP, your agent pays per query. No accounts, no API keys, no tier commitments. The agent calls any blockchain data provider, pays with a stablecoin transfer on Tempo, and gets the data back in the same response.

**Tempo Charge** is a natural fit for data queries: each request has a known cost, settlement takes ~500ms, and the agent only pays for queries it actually makes.
